Spark is the SMS & OTP delivery platform from Jain Software — engineered so growing businesses can send critical messages fast, stay DLT-compliant, and see exactly where every rupee goes.
Most SMS panels treat billing as a black box. You send a message, some credits vanish, and reconciling what was actually delivered — especially for Hindi and regional-language content — is guesswork. We thought businesses deserved better.
Spark bills every message by its real unicode segment count, shows the encoding and credits for each send, and keeps an immutable ledger of every deduction and top-up. When your finance team asks where the credits went, you have an exact answer — down to the last one.
From a single app sending OTPs to enterprises running multi-brand campaigns.
Instant, reliable login OTPs and transaction alerts your users never miss.
Order updates, delivery alerts and promotional campaigns — in any language.
Notices, approvals and reminders to large member bases, with full audit trails.
